  • Question 1
    1 / -0
    If a honey bee is conveying an information, by round dance then the distance of source will be about 
    Solution
    The round dance is performed by the worker bees when the food source is within a 50 metres of the hive. The bee runs one way in the circle, stops and then runs the other way. During the dance the worker bee passes a sample of the nectar to the other workers so they know the taste and smell of the source.
    Therefore, the correct answer is option B.
  • Question 2
    1 / -0
    Domestication of honey bee is called as 
    Solution
    Beekeeping or apiculture is the maintenance of honey bee colonies, commonly in hives, by humans in order to collect their honey and other products that the hive produces (including beeswax, propolis, pollen, and royal jelly), to pollinate crops, or to produce bees for sale to other beekeepers. Thus, the correct answer is option B.
  • Question 3
    1 / -0
    Honey is collected by ................
    Solution
    Bees visit flowers to collect nectar. With its long tongue, a honeybee extracts the nectar and stores it within its body until it returns to the hive. While inside the bee's body, the nectar combines with special enzymes that change its chemical properties so it becomes ready for extended storage. The honeybee regurgitates the nectar after returning to the hive, and another worker bee will deposit the nectar into a honeycomb. To change the nectar into honey, worker bees hasten the evaporation process by using their wings to fan air around the honeycomb. After the removal of nearly all of the water from the nectar, it becomes honey. At this point, the honeybees secrete a liquid over the honeycomb to seal it. This liquid hardens and becomes beeswax, which keeps moisture and air from reaching the honey.
  • Question 4
    1 / -0
    Which is a product of insect body?
    Solution
    Honey bee produces lots of products which includes honey, beeswax propolis, royal jelly etc. Silk is natural protein fiber produces by Bombyx mori insect. Lac is the resinous secretion produced by lac insect Kerria lacca. Therefore, the correct answer is option D.
  • Question 5
    1 / -0
    Best aquarium is located at ..............
    Solution

    Taraporewala Aquarium, situated in the city of Mumbai, India. It is the country's oldest and one of the city's main attractions. it hosts marine and freshwater fishes. The aquarium is located on the famous Marine Drive. Hence option D is correct.

  • Question 6
    1 / -0
    In which of the following, parthenogenesis is observed?
    Solution
    Parthenogenesis is a natural form of asexual reproduction found most commonly in lower organisms and plants. It is shown by honeybee, where male honeybees (drones) are produced parthenogenetically from unfertilized eggs. The only function of drones is to fertilize the queen bee. Hence, option A is correct.
  • Question 7
    1 / -0
    Which set is of beneficial insects to man?
    Solution
    Although most of the insects are not useful to us and mainly acts as a vector for many diseases like cockroach, houseflies, mosquitoes etc. There are some insects which are beneficial to man as well like honeybees which produces honey, wax etc. Lac insect (kerria lacca) is another helpful insects produces lac which is a natural protein fibre used in textile industry and cochineal insect is another helpful insect which produces red food dye. 
    Therefore, the correct answer is option A
  • Question 8
    1 / -0
    Queen is specified for 
    Solution
    The queen bee is the most valued bee in the whole hive. A queen bee can live for 3-5 years. The main job of queen is to lay eggs. The queen mates only once with several male (drone) bees, and will remain fertile for life. She lays up to 2,000 eggs per day. Hence, option C is correct.
  • Question 9
    1 / -0
    In honey bee, drones are produced by
    Solution
    Drones are male honey bees which are the product of an unfertilized egg. Drones do not have stingers and do not participate in nectar and pollen gathering. A drone's primary role is to mate with a fertile queen. 
    Therefore, the correct answer is option A.
  • Question 10
    1 / -0
    Most herbicide interfere with
    Solution
    Herbicides, also commonly known as weed killers, are pesticides used to kill unwanted plants. Selective herbicides kill specific targets, while leaving the desired crop relatively unharmed. Some of these act by interfering with the growth of the weed and are often synthetic mimics of natural plant hormones. A large number of different herbicide classes inhibit photosynthesis by binding to the quinone-binding protein, D-1, to prevent photosynthetic electron transfer. Mostly they interfere with photolysis of water. Thus, option C is correct. Herbicides does not interfere with water absorption, translocation of sugar and CO$$_{2}$$ absorption. Thus, other options are wrong.
